Google Glass enthusiasts make it sound like everyone will soon be wearing a glasses frame able to project a tiny display. None of this is breakthrough technology; it’s dependent on massive storage capacity and ultra-fast processing by somebody’s data service somewhere, like Google, or the NSA.
A competitor has a different approach: Smart glasses from Vuzix.com are aimed at surgeons, mechanics and others whose hands are too busy to pull a phone out of their pocket. Built-in apps are tailored to specific professions, or you can use one of the thousands of existing Android apps. Voice recognition by Nuance, the company that makes Dragon Naturally Speaking, is built into the glasses, so you don’t need a connection to your phone. You’ll be able to say things like “scroll left and select application.” The price is $1000, or $500 less than Google Glass.
